An ache in your lower back, a pain in your neck, a cramp in your leg ... it's hard to believe sitting at your desk can cause so much pain. Bad body posture and repetitive movements can cause almost every part of your body to hurt and every aspect of your computer workstation setup can impact your comfort level. Continually reaching for objects, tilting your head to hold the telephone on your shoulder and resting your wrist on the sharp edge of your desk are just some of the ways pain is invited to knock at your door.
